[ARM Support] Raspberry Pi 3 B+ build successful, execution error

[kravens]

General Description

After building WalletWasabi.Gui on the RaspberryPi and run it the following error occurs:
pi@raspberrypi:~/WalletWasabi/WalletWasabi.Gui $ dotnet run

Unhandled Exception: System.BadImageFormatException: Could not load file or assembly '/home/pi/WalletWasabi/WalletWasabi.Gui/bin/Debug/netcoreapp2.2/WalletWasabi.Gui.dll'. An attempt was made to load a program with an incorrect format.

How To Reproduce?

1. Install DotNet 2.2.203 ARM32
   403 mkdir -p $HOME/dotnet && tar zxf dotnet-sdk-2.2.203-linux-arm.tar.gz -C $HOME/dotnet
   404 export DOTNET_ROOT=$HOME/dotnet
   405 export PATH=$PATH:$HOME/dotnet
   406 dotnet
2. Build WalletWasabi.Gui
   git clone https://github.com/zkSNACKs/WalletWasabi.git --recursive
   cd WalletWasabi/WalletWasabi.Gui
   dotnet build
3. Run WalletWasabi.Gui
   dotnet run

ARM is not supported by Wasabi, but I guess you know that. I've never tried to build it to ARM though (or any software.) So I am unfamiliar with the error message.

Also Wasabi doesn't support x86 either, only x64. I am not sure if we have anything in Wasabi's codebase to justify this. Probably.

Also two dependencies: Tor and HWI - hardware wallet integration can be issues.

I'm afraid what you are doing won't be simple, and will require a fair amount of coding. Anyway get back to us with the results if you can progress further.

Perhaps I should first test the HWI scripts with Python and hardware-wallet, Tor should also run on ARM I believe. *Tor browser bundle also lacks RBPi3/ARM support!
I agree that we don't need ARM support for now, as people concerned with coin-joining should be able to afford a decent 64-bit personal computer ;-)
But could have been a nice educational project!

This might be possible now with DotNet 3 and Avalonia 9?

Can someone confirm? @jmacato maybe

[kravens]

Let me try to build / run the latest master repository :)

[jmacato]

This is possible but i cant test coz i dont have RPi at hand right now :)
